Abstract
A dispelling pen including a pen case and a pen head connected with the pen case, wherein at least one accommodation cavity for storing a dispelling solution is disposed in the pen case. The accommodation cavity is connected with the pen head via a pipeline. A switch control valve is disposed on the pipeline. The dispelling pen need not frequently dip in the dispelling solution, thereby avoiding fragmentation and circuit scratch due to the dispelling pen's repeated contact with the substrate while increasing convenience significantly, and increasing the security of the substrate at the time of dispelling.
